In traditional, the working probe naturally sustaining repeated bending actions and wear, absolutely needs a mechanism to prevent it from being damaged, caused by the change of the probe's geometry and the increase of the contact resistance. Therefore, in this study, we develop a CMOS-based chip in connection with the electroformed probes to detect each of their counterforce, contact resistance to evaluate if their contact force and coplanarity are controlled within safe range.
传统上,探针常因为弯曲作动和磨耗,使几何形状产生改变,进而电阻值提升,使过大的电流通过探针而烧毁,或因共面度不佳部分探针未能确实接触IC焊垫误判成断路,故晶片的制作重点在於监测探针卡上个别探针的回馈力量,当探针量测IC时,可进行即时探针反作用力、接触电阻的检测,进而了解探针卡工作时受力是否均匀、平坦度是否符合要求等性质。

The rheological character of a polymer often appears as shear-thinning. Most polymers behaviour in a solution can be explained by the polymer chain or hard sphere theory. Other than that, shear-thickening polymer solution also exists. Its behavior can be explained by dilatant theory, which suggests that the shear-thickening of the solution is due to the swelling of the polymer particles. This phenomenon often occurs in suspension or emulsion. Solution exhibits a mixed behavior can also be found whose behavior is such that shear-thinning occurs under low shear force and shear-thickening occurs under high shear force. Under this circumstance, the viscosity versus shear force graph exhibits a spoon shaped curve. The rheological study can be applied to the dispersion of paint which can predict the dispersion effect of various polymer materials in solution.
中文摘要一般高分子聚合物溶液的流变行为多半呈现剪稀(shear-thinning)的现象,而大部分的高分子在溶液中的行为是以分子链或是硬球观点来解释,另外也有剪稠(shear-thickening)现象的高分子溶液,其流变行为则是以膨胀体观点来解释,即在高剪切力下,由於高分子团体积变大而使溶液黏度升高,这在悬伏液、乳液等常见;但也有在低剪切力下,溶液具有剪稀的行为,而在高剪切力下却成现剪稠的行为,在黏度对剪切力作图时,会呈现出一个勾形曲线的图形;流变行为的探讨可应用在涂布材料的分散技术上,以推测不同的高分子溶液对分散效果的影响。

By use of the Fischer-Tropsch reaction in a C-H-O system, we discussed the relationships between inorganic CO〓 and some physical chemistry conditions, such as Oxygen flee degree , temperature, pressure, other objects consistency and catalyzer. a when T=200K~2000K, if f〓>0, the reaction of generating CO〓 will be dominant, CH〓 hardily exists; b when T>1000K, CH〓 is not propitious to exist, carbon in system almost exists in form of CO〓; c the more pressure, the more CO〓 is propitious to exist; d the more consistency of CO, O〓 and H〓O, the more CO〓 is propitious to exist, the more consistency of H〓, the more CH〓 is propitious to exist.
依据C-H-O体系费托反应的简化模型,讨论了氧逸度、温度、压强、其它物质浓度、催化剂等物理化学条件对无机成因CO〓生成的影响,从理论上讨论了在地质环境中,无机成因CO〓存在的物理化学条件:1在T=200K~2000K的温度范围内,体系中一旦氧逸度>0,生成CO〓的反应将占绝对优势,CH〓几乎不可能存在;2T>1000K时,不利于CH〓形成,使体系中的碳主要以CO〓的形式存在;3体系压强越大,越有利于CO〓的形成;4反应物CO、O〓、H〓O的浓度越高,越有利与CO〓的存在,H〓的浓度高有利于CH〓的形成。5地质成藏作用可以经历很长的地质年代,这足以补偿矿物岩石中的Ni、Mo、Fe、Co、Ru等催化性能的降低及其它动力学条件的不足,使得费托反应可能发生,从而生成无机成因的CO〓和烃类。

Soluble cycloaddition derivatives of 〓aresynthesized by the reaction of 〓 with indene,1,1'-biindene andcyclopentadiene derivatives.〓Particular, the Diels-Alder cycloaddition of 〓 with1,1'-biindene under controlled conditions affords the stable monoadduct 〓〓of novel structure, which was confirmed by HPLC, FTIR, FD-MS,〓NMR,〓 NMR, HMQC and HMBC spectra, Its two bridgehead cage carbons resonate at70.91ppm, The 〓 NMR spectra showed 38 lines consistent with the 〓 symmetryassociated with [6,6] addition. The 〓 shows similar optical limitingproperties to that of 〓 in toluene for 8ns laser at wave length 532nm. Moreover, thehigh solubility of this adduct in polar solvents such as THF, acetone enables itsincorporation into sol-gel glass matrix. The thin films prepared via the sol-gel methodshow improved OL behaviour compared to those of 〓. The langmuir-Blodgett filmformation and uv-visible absorption of 〓 are also investigated. LBmonolayer of this compound is prepared on the air-water interface at 〓 mol/l. In chapter 4, three water-soluble derivatives of [60] fullerene: fullerol(1), theaddition product (2)of fullerol (1)with polyvinylpyrrolidone and fumaric acidderivative of 〓(3) are synthesized and characterized.
